Question

Im try to create a spinner dynamically on press of a button.

this is what i did:

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.leave_balance);

spinner = new Spinner(this);
    ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item, list);
    spinner.setAdapter(spinnerArrayAdapter);

Button  b = (Button)findviewbyid(R.id.button1);
b.setonclicklistener(new Onclicklistener){
   public void onClick(View v) {
            spinner.performClick();


        }
 spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            Toast.maketext(context,"selectedspinner",Toast.LENGTH_SHORT).show();

        }

        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });
}
}

My issue is im not able to get that toast, ie the spinners onitemselectedlistner is not triggering.

Any suggestion will be greatly appreciated.. Thanks

Answer 1

Spinner need to add in a parent to get call on onItemSelected

1. Add the sppiner in XML and set width and height 0dp (may set visibility Invisible not gone).

2. Get that using findViewById.
